After installing the latest Nvidia drivers (390.25-226) on my Optimus laptop running Solus Plasma from the latest preview ISO, I'm experiencing a number of graphical "glitches" - UI element spacing and text are all shrunk down and animations like NetworkManager's spinner when connecting to a network are sped up - NM's spinner looks more like a solid circle than a loading animation, it goes so fast.
The issue gets fixed when the Nvidia drivers are removed, so I know it is an issue related to the drivers/LDM, but it is also a Plasma issue because this didn't happen on Budgie. Last tested after today's (2/26/2018) updates.
Screenshots are attached.
